## Issue Addressed Closes #1504 Closes #1505 Replaces #1703 Closes #1707 ## Proposed Changes * Update BLST and Milagro to versions compatible with BLSv4 spec * Update Lighthouse to spec v1.0.0-rc.0, and update EF test vectors * Use the v1.0.0 constants for `MainnetEthSpec`. * Rename `InteropEthSpec` -> `V012LegacyEthSpec` * Change all constants to suit the mainnet `v0.12.3` specification (i.e., Medalla). * Deprecate the `--spec` flag for the `lighthouse` binary * This value is now obtained from the `config_name` field of the `YamlConfig`. * Built in testnet YAML files have been updated. * Ignore the `--spec` value, if supplied, log a warning that it will be deprecated * `lcli` still has the spec flag, that's fine because it's dev tooling. * Remove the `E: EthSpec` from `YamlConfig` * This means we need to deser the genesis `BeaconState` on-demand, but this is fine. * Swap the old "minimal", "mainnet" strings over to the new `EthSpecId` enum. * Always require a `CONFIG_NAME` field in `YamlConfig` (it used to have a default). ## Additional Info Lots of breaking changes, do not merge! ~~We will likely need a Lighthouse v0.4.0 branch, and possibly a long-term v0.3.0 branch to keep Medalla alive~~.
